WOVEN FABRIC.

SPECIFICATION forming part of Letters Patent No. 666,253, dated January 22, 1901.

Application filed June 8, 1900. Serial No. 19,593. (Specimens-l To a, whom it may concern:

Be it known that I, WILLIAM AEBERLI, a citizen of the Swiss Republic, residing at Paterson, Passaic county, State of New Jersey,

have invented certain new and useful Improvements in Woven Fabrics, of which the following is a specification.

My invention relates to weaving, and has for its object to improve the construction of IO tissues produced upon needle-looms.

The invention will be fully described hereinafter by referring to the accompanying drawings and diagrams, which illustrate, diagran'lmatically, a fabric made in accordance with my invention.

By needle-loomsI mean looms which employ a needle or needles to carry the filler back and forth through the shed and which employ needles at the edges of the fabric to hold the loops of the filler-threads until the said filler-threads are bound in by the warp.

In needle-looms as now-constructed no adequate means are provided to draw these loops into the edge of the fabric, and consequently 2 5 the edges of the fabric are marred by these minute projecting loops. These projecting loops are objectionable, and by myinvention I am enabled to entirely get rid of the said loops. This I do by providing at the edges of the fabric an additional set of warp-threads, with which the filler-threads are bound,which warp-threads are held at sufficient tension to draw the loops firmly to the body of the fabric when they are released by the forming- 5 needles.

In the accompanying drawings, Figure 1 is a textile view showing the course of the threads in my novel structure. This view is diagrammatic merely, and the loops at the edges are left projecting in order to clearly show the course of the threads. In practice these loops are drawn into the edge, as will be explained. Figs. 2, 5, 4, and 5 are diagram matic drawings showing the course taken by the threads at the various picks.

In the figures I have shown a fabric having its edge constituted by a double Weave, with an additional or pulling-in weave between the double weave. The warp-threads of the top weave of the edges are indicated by the reference-letters a, the warp-threads of the bottom weave of the edges are indicated by the reference-letters b, the weftthreads of the right-hand needle are indicated by the letters a, the weft-threads of the left-hand needle are indicated by the reference-letters g, and the additional or pullingin warps are indicated by the letter The character of the fabric may best be disclosed by describing the course of the threads at the various picks. Let us start in from the right. (See Fig. 2.) The first pick comes from the right, (the doubled thread 0,) is woven in with the weft-threads ct of the top weave on the right side or edge, is woven in with the body or ground of the fabric-to wit,the Warpthreads eand is then woven in with the warps of the middle or pulling-in weave of the edge at the left side-to wit, the threads fleaving a loop at the left side of the fabric on the needle (I, which loop is pulled in by the warps of the middle or pulling-in weave when the needle releases the lo0p-weft,s0 that the aspect of the edge is not marred by a projecting loop. The second pick comes from the left, (the doubled thread 9,) is woven in the upper edge weave at the left edge of the fabric, is woven in with the ground weave in the body of the fabric, and is Woven in with the middle weave at the right edge of the fabric, the loop when released by the edge forming needle being drawn in by the Warpsf of the said weave. These various operations will be found graphically illustrated in Fig. 2. The third and fourth picks are shown in Fig. 3, in which the third pick is woven in with the bottom weave on the right side of the fabric, the ground or body, and the middle weave on the left side of the fabric. At the fourth pick the thread g is woven in with the bottom weave on the left-hand side of the fabric, with the ground or body weave and with the middle weave on the right-hand edge of the fabric. In Fig. 4 at the fifth pick the doubled thread 0, coming from the right, is '5 woven into the top weave at the right-hand edge, the body weave and the middle weave at the left-hand edge, and at the sixth pick the doubled thread g, coming from the lefthand side, is woven in with the top Weave at the left-hand edge of the fabric, the ground or body weave and the middle weave at the right-hand edge of the fabric, the fifth and sixth picks being similar to the first and second. In Fig. 5 I have shown the seventh and eighth picks, which are similar to the third and fourth, respectively. In this manner each weft or filler thread is woven in with the respective edges, the loop ends of the fillerthreads being woven in with the middle weaves of the said edges, whereby the loops are drawn in to the edge.

It will be observed that the fabric which I have described is capable of many variations without departing from the spirit of my invention, which is essentially to bind in the loop ends of the double weft-threads by an extra weave. It will likewise be observed that in the form of my invention illustrated in the drawings the top and bottom weaves are each made with a less number of picks than the whole number. In this case the top and bottom weaves are each made with onehalf of the whole number of picks.

While I have spoken of three weaves in the selvage edge and have diagrammatically illustrated the same, it must be understood that the illustrations are technical diagrams merely and are addressed to those skilled in the art. It is well known that a weave such as is described by me has at each edge a small tube formed by the joined edges of the top and bottom weaves, within which tube are the middle Weave or warp-th reads, which by their tension serve to draw in the needle-loop from the edge of the fabric.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. A fabric having a doubled filler-thread and a double-weave edge having additional warp-threads to draw in the filler-loop.

2. A fabric having an edge formed of three weaves and doubled-thread fillers woven in with the face and middle weaves.

3. A fabric having doubled-thread filler and an edge containing extra threads to draw in the filler-loop.

4.. A fabric having extra threads at its edge and a doubled filler having its loop end woven in with the extra threads.

5. A fabric having doubled filler-threads and a double-edge weave, the loop ends of tbe filler lying between the double weaves of the edge and the loops being drawn in or nonprojecting.
